HARVEY D. HARMER, OF COUNCIL BLUFFS, IOWA, ASSIGNOR OF ONE-HALF TO EDWARD W. HART, OF SAME PLACE.

NIPPLEfHOLDER.

SPECIFICATION forming part of Letters Patent No. 407,292, dated Tuly 16, 1889.

Application filed April 29, 1889. Serial No. 309,053. (No model.)

To all whom it may concern:

Be it known that I, HARVEY D. HARMER, a citizen' of the United States, residing at Council Blus, in the county of Pottawattamie 5 and State of Iowa, have invented certain new and useful Improvements in Nipple-Holders,

of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this speciro ication, in which Figure 1 is a side view of a nipple-holder with my improvement attached. Fig. 2 is a vertical section through Qc of Fig. l. Fig. 3 is the spear-head detached.

15 The object of myinvention is an improved means for holding a nipple while the lefthand thread is being cut, the right hand thread having already been cut; and it consists in the combination of devices herein- :o after explained and claimed.

To enable others skilled inthe art to make and use my invention, I will now describe the manner in which I carry the same out.

In the drawings, A represents the main 2 5 tube, and a the nipple to be cut. The upper end of the tube is internally threaded to receive the right-hand screw on the lower end of the nipple. It is evident that any attempt to cut the left-hand screw on the upper por- 3o tion of the nipple would cause the right-hand screw to turn, which would Withdraw the nipple from the holder. Tov prevent this is the special obj ect of my invention.

Inthe lower end of the tube A, I rigidly secure a smaller tube B, internally screw- 5 threaded, and through this I pass the rod C, threaded to fit the female screw in the tube B. On this rod I secure a handle c for turning the rod, on the end of which I secure the swivel D, and attach this to the lower end of 4o another rod E, which carries on its upper end a spear-pointed head F, which moves up and down in slots e. This spear-head has sharp beveled edges f, and when by turning the handle c the rod E is forced upward the spear- 4 5 head F is driven into the lower end of the nipple, whereby the nipple having been screwed down into the tube is caught and y firmly held by the sharp edges of the spearhead during the operation of lcutting the left- 5o hand screw on the upper or exposed portion of the nipple.

' After the thread has been cut it is only necessary to reverse the movement of the handle c, draw down the spear-head, and re- 55 move the nipple from the tube A.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

In a nipple-holder, the tubes A and B and 6o the threaded rod O, in combination wit-h the swivel D and spear-headed rod E, all constructed and arranged substantially as and for the purpose described.

HARVEY D. HARMER.
